Specification of Letters Patent.

Patented Nov. 2', 1909.

citizen of the United States, and resident of the boron h of Manhattan,city, county, and State of ew York, have invented certain new and usefulImprovements in Guard- Rail Clamps, of Wll'lCh the following is aspecification, reference being had therein to the accompanying drawings,in which Figure l isan end elevation showing the clam applied; Fig. 2aplan view, the heads of t -e track rail and the guard rail" beingremoved and the arm of the locking block being shown in section to" moreclearly show the construction of the device; Fig. 3 a detail perspectiveView of one of the spacing pieces employed; Fig. 4 an end elevationshowing the ard rail clampin position; Fig. 5 a detai vertical sectionalview on the line V-V of Fig. 2; Fig. 6 a detail side elevation of aportion of the clamp yoke; Fig. 7 a detail perspective viewof the clampwedge; and F 1g. 8 a plan View showing a modified form of the 0 amplocking-block.

. This invention relates to that class of devices known as guard railclam s, and which are used for the urpose o clampin a ard rail to the ajacent track rail, a n ler lock or spacing means being interposedbetween the two rails to' hold them a fixed distance from each other.

One of the objects of this invention is to provide means by which theclamp may be clamping means to thetie, or keying or o'lting it to theard rail.

Another 0 ject of the invention is to provide means whereby the clampwill be held tightly in "lace by a wedge and thawed e will be Iocposition by a locking evice, said device ing inturn connected to anysuitable means.

Referring t6 t evarioif'is parts by numer- Ms, 1 designates "the wickrail and 2' the guard rail. To space the guardrail a suitable distance--from the. track rail employ the twoart filler block 3. This bloc' iscomposed of two arts, 4 and 5,which are ll jv on a diagonal line, the

'ooved vertically so that the two parts the e interlocked-to preventindependent en wise movement of said sections or members.

The member 4 is provided mid-way bedinal line of the guard rail, asshown tom of sai tween its upper and lower edges with an outwardextending horizontal rib 6 which extends the entire length of the block;and the co-ac'ting member 5'is formed with a cor responding groove 7 toreceive said rib, whereby the two members will be held againstindependent vertical movement. The member 4 is considerably longer thanthe member 5 to provide for a-considerable range of adjustment. It will'be seen that by adjusting the blocks on each other the uard rail may bespaced various distances rom the track rail. The shorter member 5 isprovided with depending lugs 8 which engage the sides of the clamp barproper shaped arm 12, the end 0 said arm turned inwardly toward theguard rail, its vertical face 13 being oblique to the longitpclear y inig. 2. This vertical face is cut out from the 11 per surface of the arm12 downward a suita 1e distance to .form the. horizontal shoulder 14.Said arm is also undercut fromthe end of the shoulder 14 to form thewedge surfaces 15 and 16, said surfaces being parallel with theoblique'fa'ce 13 of the arm.

' In the space between the guard rail and the end of the arm 12 isfitteda clamping wedge 17. This wedge bears against the Web of the guard railand is formed with the ontward extending wedge portion 18 at its lowerend, said wedging portion being formed with the surfaces 19. and 20which engage the corresponding surfaces 15 and 16 of the clamping yoke,said surfaces 19 and 20 being oblique to the vertical face 21'whichengages the web of the guard rail and c orre-' sp'on ing to theinclination of the oblique faces of the clam yoke. The wedge block isalso formed'wit an oblique .face 22 which is verticall corrugated asshown, the bot;

corru ations being in substantially the same hor zontal plane as theshoulder 14.

' ment on' the clamp.

as at 24 to adapt it to engage the similarly corrugated face 22 of thewedge block. The locking block 23 is provided with an outwardly.extending arm 24 adapted tolie against the side of the clamp yoke, saidarm being slotted at 26 for the passage of a securing bolt 25 and toermit of its adjusthe arm 12 of the clamp yoke is formed with anaperture for the passage of the securing bolt 25.

' Should it be impossible to drive the wedge inwardly sufliciently topermit the ribs on the lockmg block to enter the desired grooves in thewed'ge I provide a spacing strip 27 which may be inserted between" theface 13 of the yoke and the outer or rear face of the locking block, asshown clearly in Figs.'2 and 5. These spacing strips maybe provided witharms 28 extending outwardly and adapted to lie against the sideof theclamp wedge, sai arms bein slotted forithe passage of the'securing olt25,'as shown in %n Fig. 8 the locking block 23 is provided with two arms24 which embrace the sides of the arm 12 of the clamp yoke. This form oflocking block may be employedinstead of the formshown in Figs. 2 and 4,it being, of

course, understood that I do not wish to be limited to an specific-formof locking block, except as t e same may be specifically claimed herein.

In assembling the clamp the wed e is driven in between the clamp yokeand the guard rail and then the locking block -is r'iven down betweenthe face 13 of the clamp and the face 22 of the wedge,the ribs andgrooves on the engagin faces of the two parts interlockin there holdingthe wedge in its lo ed position. When the locking block has been drivendown to its final position the securing bolt 25 is inserted and boltedto the yoke. g Y

' In order to strengthen the lockin block and'to provide a surface thatmay be stantly struck in drivin 'the locking block in place I form saidbloc with an outwardly extending stren hening cap or flange 29 which isada te .to extend outward over the 11 per end 0 the 'arm 12 as shownclearly in l -laving thus described my invention what I claim as new anddesire to'secure by Letters Patent is 1.
